LOG: [LLDB] Fix buffer overflow problem in DWARFExpression::Evaluate

In two calls to ReadMemory in DWARFExpression.cpp, the buffer size
passed to ReadMemory is not checked and can be bigger than the actual
size of the buffer. This caused a buffer overflow bug, which we
found through Address Sanitizer. This patch fixes the problem by
checking the address size when it is first read out of the DWARF, and
setting an error and returning immediatley if the size is invalid.

This is the second attempt to fix this issue; I reverted the first one,
as it was not quite correct.

Could you split the changes to the selected thread out of this? I'm seeing two

Other than that, it looks pretty good!

I was thinking about this earlier, since we know what all the possible strings 
are going to be, we can create them all statically at compile time and just 
point to them. We can refactor a bit and then most of these source names just 
become `static const char *` or `static constexpr llvm::StringLiteral` or 
something like this.

[Lldb-commits] [PATCH] D153734: [lldb][TargetGetModuleCallback] Call get module callback

2023-07-10 Thread Kazuki Sakamoto via Phabricator via lldb-commits

splhack added a comment.

@clayborg 
Sure, I'll rename the type and function to `Locate` instead of `Get`.

  typedef SBError (*SBPlatformLocateModuleCallback)(
  SBDebugger debugger,
  SBModuleSpec &module_spec,
  SBFileSpec &module_file_spec,
  SBFileSpec &symbol_file_spec);

This `SBPlatformLocateModuleCallback` typedef is required for the SWIG type 
conversion.

However it will introduce the SB* dependencies to `Platform.h` if we use the 
type. Is it ok?

  void SetLocateModuleCallback(SBPlatformLocateModuleCallback callback, void 
*baton);

I think `Platform.h` should use `void *` instead of 
`SBPlatformLocateModuleCallback`. Is it correct?

  void SetLocateModuleCallback(void *callback, void *baton);

There was another reason why `Debugger` has this method. The reason was that 
`Debugger` is easily `gMock`-able but `Target` is not.
Please take a look at `MockDebugger` in 
`lldb/unittests/Target/GetModuleCallbackTest.cpp` in this diff.

I will update this diff to allow C function callback aside from Python 
function, but probably we need to keep this kind of method outside `Target` for 
`gMock` to write unit tests.

2023-07-10 Thread Jason Molenda via Phabricator via lldb-commits

jasonmolenda added a comment.

I guess simplest is we can have all the UnwindPlan creators have a `static 
g_unwindplan_name` and save a pointer to that.  Each one is unique, don't need 
anything fancier than that. There's the risk that someone will create a new 
UnwindPlan and forget to make it a static string, so unwind logging would try 
to print random memory, but it wouldn't break normal debugging.

2023-07-10 Thread Jason Molenda via Phabricator via lldb-commits

jasonmolenda added a comment.

probably the real correct change is to have constant c-strings in as globals 
and have pointers to those.  Then you're using the same space as a ConstString 
in each UnwindPlan (a pointer) but creation is cheaper.  There's no dynamic 
aspect to the names when the UnwindPlans are created, each method creating them 
knows what the name will be.

(to say it more clearly: I'm fine if you'd like to reduce the places where 
ConstStrings are being used, but I don't think there's any good reason to 
remove this use of them.  It will increase our memory footprint a bit.)

jasonmolenda accepted this revision.
jasonmolenda added a comment.
This revision is now accepted and ready to land.

I'm fine with this.  It does increase the size of the UnwindPlan object, and 
there are a couple of them for every function that we see on a stack during a 
program execution, but I believe that won't be more than a few hundred.  These 
are short strings so they won't expand to use heap, they will fit inline.  
Strictly I think it is more memory efficient to leave these half-dozen strings 
in the constant string pool than to have an extra 24 bytes in each UnwindPlan 
with them duplicated, but it's not enough memory use for me to be actually 
worried about it.

[Lldb-commits] [PATCH] D153734: [lldb][TargetGetModuleCallback] Call get module callback

2023-07-10 Thread Greg Clayton via Phabricator via lldb-commits

clayborg requested changes to this revision.
clayborg added a comment.
This revision now requires changes to proceed.

So the "SetTargetGetModuleCallback" functions in this patch need to pass both a 
callback _and_ a callback_baton. That way people can register native callbacks 
that can be used. The python interpreter, when SetTargetGetModuleCallback is 
called from python, can take care of registering a callback that will call 
through the interpreter. See the following function as a model to follow:

  void SBDebugger::SetDestroyCallback(lldb::SBDebuggerDestroyCallback 
destroy_callback, void *baton);

See this patch for details:

  $ git show b461398f1ce30




Comment at: lldb/include/lldb/Target/Platform.h:888
+  /// from symbol servers.
+  void SetTargetGetModuleCallback(void *callback_baton);
+

You actually need a callback along with the baton here. We probably don't need 
the word "Target" in the function name?

Maybe better named as 
```
void SetLocationModuleCallback(PlatformLocateModuleCallback callback, void 
*baton);
```



Comment at: lldb/include/lldb/Target/Platform.h:890
+
+  void *GetTargetGetModuleCallback() const;
+

Usually there there are two functions:
- one that returns the function callback
- one that returns the callback baton



Comment at: lldb/include/lldb/Target/Platform.h:939
   const std::unique_ptr m_module_cache;
+  void *m_target_get_module_callback_baton = nullptr;
 

We need to store the callback itself here too. Remove "target" from the name



Comment at: lldb/source/Core/Debugger.cpp:2170-2181

+  if (!script_interpreter)
+return Status("Cannot find ScriptInterpreter");

I don't think we need any of this in debugger. when someone, through python 
calls the "SetTargetGetModuleCallback" that code should register a static 
function as the callback to use that will end up calling into the script 
interpreter.

We don't always want to call the script interpreter for all cases. Users should 
be able to register a native callback for this, and it shouldn't force us to 
always use the script interpreter.

[Lldb-commits] [lldb] fb10b01 - [lldb] Prevent crash when completing ambiguous subcommands

LOG: [lldb] Prevent crash when completing ambiguous subcommands

Fix a crash when trying to complete an ambiguous subcommand. Take `set s
tar` for example: for the subcommand `s` there's ambiguity between set
and show. Pressing TAB after this input currently crashes LLDB. The
problem is that we're trying to complete `tar` but give up at `s`
because of the ambiguity. LLDB doesn't expect the completed string to be
shorter than the current string and crashes when trying to eliminate the
common prefix.

LOG: "settings set -g target.load-script-from-symbol-file" shouldn't crash.

-g is specified by passing in nullptr ExecutionContext, but in some
load-script-from-symbol-file specific code, the ExecutionContext was
asked for its Target w/o checking whether the pointer was null.

Fix that and add a test.

  - ``-fdouble-square-bracket-attributes`` has been deprecated. It is ignored 
now
and will be removed in CLang 18.

sounds good. (Minor case typo in `CLang`). As you said in

https://discourse.llvm.org/t/rfc-enable-c-11-c2x-attributes-in-all-standard-modes-as-an-extension-and-remove-fdouble-square-bracket-attributes/71268/2

I think a clear summary/commit message should mention that this patch makes 
`[[...]]`` available to C++03 and C17 with no warning by default.

It's also worth calling out that GCC since 10 supports `[[]]` in all C language 
modes (AFAICT there is no warning even with `gcc -std=c89 -c a.c`) (there is a 
warning `-pedantic`).

  % g++ -c a.cc -std=c++03
  a.cc:2:1: error: expected unqualified-id before ‘[’ token
  2 | [[nodiscard]] int without_underscores(void);
| ^
  % myclang++ -c a.cc -std=c++03  # no warning with this patch

This revision is now accepted and ready to land.

This looks like it might be the place where we also say "`set s` could either 
be `set` or `show`".  But that's actually done elsewhere so this change is 
okay.  We should maybe make sure we have a test for `setting s` -> {`set` 
or `show`} options.

A common thing to do is to call `str().c_str()` to get a null-terminated
string out of an existing StringRef. Most of the time this is to be able
to use a printf-style format string. However, llvm::formatv can handle
StringRefs without the need for the additional allocation. Using that
makes more sense.

[Lldb-commits] [PATCH] D154883: [lldb][NFCI] Methods to load scripting resources should take a Stream by reference

bulbazord requested review of this revision.

Herald added a project: LLDB.

These methods all take a `Stream *` to get feedback about what's going
on. By default, it's a nullptr, but we always feed it with a valid
pointer. It would therefore make more sense to have this take a
reference.

[Lldb-commits] [PATCH] D151683: [clang] Enable C++11-style attributes in all language modes

2023-07-10 Thread Aaron Ballman via Phabricator via lldb-commits

aaron.ballman added a reviewer: MaskRay.
aaron.ballman added a comment.

Aside from the failing precommit CI test case in C, I think this LGTM. I've 
added @MaskRay as the code owner for the command line option changes in case 
he's got concerns regarding the deprecation/removal plans.

[Lldb-commits] [lldb] 1e7101a - [lldb][NFCI] TestEmulation should take a Stream ref

LOG: [lldb][NFCI] TestEmulation should take a Stream ref

`Instruction::TestEmulation` takes a `Stream *` and checks it for validity.
However, this is unnecessary as we can always ensure that we never pass
`nullptr` for the `Stream` argument. The only use of
`Instruction::TestEmulation` currently is `SBInstruction::TestEmulation`
which gets the `Stream` from an `SBStream`, and `SBStream::ref` can
return a `Stream &` guaranteed.

[Lldb-commits] [PATCH] D154823: [lldb][AArch64] Add test predicate for systems with SME enabled

"sme" is just one of many cpuinfo features for SME but it's the
only one we need for testing.

The rest are related to the use of certain instructions and
don't change the register state available.
